我国自60年代开始推广高粱杂交种以来,高粱产量成倍增长,这主要是杂种优势的发挥。然而,在高粱栽培技术和培栽生理研究上没有多少进展,一如既往地应用着传统的耕作管理方法(分期追肥,等行种植,老熟收获、种子不消毒等),使优良品种的增产潜力不能得以充分发挥,限制了高粱生产发展。为此,高粱研究所高粱栽培研究室,从1982年开展了高粱综合技术栽培的研究,运用现代栽培技术与传统的耕作经验相结合,采用播前一次深施足 Since China began to promote sorghum hybrids in the 1960s, the yield of sorghum has doubled, mainly because of the heterosis. However, little progress has been made in the field of sorghum cultivation and physiology of cultivation. As usual, traditional farming methods (top-dressing, planting in rows, harvesting of mature plants, non-sterilizing of seeds, etc.) have been applied, so that the yield potential of fine varieties can not be increased To give full play to limit the development of sorghum production. To this end, sorghum Institute of sorghum cultivation laboratory, carried out in 1982 from a comprehensive study of sorghum cultivation, the use of modern cultivation techniques and traditional farming experience combined with the sowing before the implementation of a deep enough
